Also known as: Yarrow, Milfoil, Thousand-leaf, Achillea millefolium

Overview

Yarrow (*Achillea millefolium*) is a perennial herb belonging to the Asteraceae family, recognized for its medicinal properties and extensive use in both traditional and modern medicine. It is rich in bioactive compounds, including phenolic compounds like flavonoids, phenolic acids, and essential oils such as monoterpenes and sesquiterpenes. Traditionally, yarrow has been used for various ailments including gastrointestinal disturbances, inflammation, wound healing, and as an anticancer agent. Its extensive pharmacological research supports its antioxidant, anti-inflammatory, and antiproliferative effects, although substantive clinical trials are still needed to ascertain definitive health benefits and safety in human populations.

Benefits

Yarrow exhibits multiple health benefits, each supported by varying degrees of evidence. Key benefits include: 1. **Antioxidant Activity:** High efficacy in reducing oxidative stress, evidenced by significant reductions in reactive oxygen species (ROS) production through phenolic compounds. 2. **Anti-Inflammatory Activity:** Reduces levels of pro-inflammatory cytokines (IL-6, TNF-α) through mechanisms that inhibit cyclooxygenase and prostaglandin E2, providing effective anti-inflammatory responses. 3. **Antiproliferative Activity:** Potential applications in colorectal cancer treatment, with studies indicating inhibition of key lipid metabolic targets. Secondary benefits include antibacterial properties against *Helicobacter pylori* and traditional applications in wound healing.

How it works

Yarrow exerts its effects through multiple biological pathways. Its anti-inflammatory actions are primarily due to the inhibition of cyclooxygenase and the reduction of prostaglandin E2, which play crucial roles in inflammation. Furthermore, its antiproliferative effects on cancer cells are mediated through the inhibition of various metabolic targets associated with lipid metabolism and cancer progression. Notably, it shows activity against bacterial growth in the gastrointestinal tract, highlighting its role in digestive health.

Side effects

Yarrow is generally regarded as safe, but it may cause side effects in some individuals. Common adverse reactions include allergic responses, gastrointestinal upset, and skin irritation, occurring in over 5% of users. Less frequently (<5%) reported are potential interactions with drugs that use Cytochrome P450 enzymes, leading to altered drug concentrations. Rare side effects (<1%) include severe allergic reactions and anaphylaxis. Pregnant and breastfeeding women should exercise caution due to limited safety data, and individuals allergic to Asteraceae should also avoid yarrow.

Dosage

Dosage recommendations for yarrow extract can vary based on the intended use and specific formulations. Typical effective doses range from 100-500 mg per day for antioxidant and anti-inflammatory effects; however, specific dose standardization is critical for consistent results. Timing considerations suggest ingestion before meals may optimize gastrointestinal benefits. Advanced extraction methods, such as supercritical antisolvent precipitation, enhance compound bioavailability, making formulations more effective.
